Interjection used in the past by Older generations
interj. • An interjection showing disbelief, annoyance, or dismay. Often used as an alternative to "my god" or other somewhat more vulgar interjections. Originated from a song by Huddie Leadbetter called "Goodnight, Irene" (1933), which was about his frustration with a past relationship. Usage is becoming obsolete.
"Did you hear that John came home drunk again last night?" "Oh, good night Irene. He never learns."
